### Instructions[](https://kittenbothk-eng.readthedocs.io/en/latest/Kits/fitness/ybalance.html#instructions)

1. Make a big Y with tape on the ground. (Approx. 1m for each sid)
2. Place the corresponding sensor on the end of each line(F,L,R).
3. Place a little box on the center of the Y.
4. The system measures the Front, Left and then Right, the controller will show the current mode.
5. Press A on the controller to set a baseline on the current mode.
6. Ask the user to push the box with his/her feet along the line, press B on the controller when the user reaches the limit.
7. Press A+B to switch modes.
8. Repeat until all 3 lines are measured, press the button module to upload the data onto MakerCloud.
